Uberschall, the German word for "Super Sonic," is really armageddon in a box. Everything this amp touches suffers an instant nuclear meltdown. Bogner designed this amp head primarily for heavy-playing, aggressive styles of music.

The Bogner Uberschall tube amp features a classic clean channel with volume, gain, bass, middle, treble, and presence controls. Pound all your pedal effects into this channel, the harder you hit it the more it smiles to show you its fangs. Bogner then unleash mayhem with the five megaton, super-aggressive high-gain channel with gain, bass, middle, treble, volume, and presence controls. You think you've heard bass before? Not like this—the Uberschall amp head will shatter your ribcage! Even with extreme gain and volume, this channel stays massively focused and resists mushing out from the heaviest right-hand attack. Have some other crazy effects? Put them through the Bogner Uberschall tube-buffered effects loop. Power comes from a throaty EL34 output section.

Go ahead, try and hide from the Bogner Uberschall it will seek you out, relentlessly, while you sleep, in this life and the next. Embrace the tube guitar amp with standard tuning, 7-string, or dropped low-tuning.

Comments about Bogner Uberschall Series 120W Tube Guitar Amp Head with EL34s:

I have owned the Revision Blue Uberschall for 3 years now, and for me it's the best amp. "Clear" distortion of that means anything to you, the notes ring out, and you can play sus-chords, full open chords on the distorted channel and they ring out. I have the matching Uberkab and it totally punches with a great low end. I like things simple, tube buffered FX loop, two channels, and a master volume. The clean isn't horrible, however you'd think they could do a bit better on it considering the name and rep of Bogner. This is not a loss though as you can put a load of pedals through the loop and it cleans up the clean channel VERY nicely. I've not had any mechanical issues, and it just punches very hard. I play a Rico Jr Hesperian 7 string with Dimarzio's through it, but really the amp can handle whatever axe and fx you wanna run through it. I would call it less compressed sounding due to the EL-34 and more of a 'breathing' high gain hard rock/metal amp. It really does have a tone all it's own. The only amp I can really compare to the dirty channel would be a Rivera Knucklehead Tre. I love this amp, and it's a fantastic, simple, great piece of equipment. Loud as hell too.

If you're looking for one of the most BRUTAL metal amps with lots of character, the Uberschall delivers. Clean channel is serene and very crisp, but the real reason people buy this head is for the gain channel. Key to this amp is to find the sweetspot with the tone controls. Gain Channel: Presence around Noon, Treble = 6-7, Middle = Between 10:00 - 2:00, Bass = 1:00, Gain = Between 11:00 - 2:00. Master volume at 11:00.
